Blows fi fuse

2 cars, which one died
never jumper cable backwards (Plus/minus) or boom , electronics blow to H3LL. sorry if happened.
or
if car 1 battery is dead and will not crank. OR LOOSE RUSTY LUGS.
we jumper it with running 2nd car and noW car 1 cranks and runs.
BUT....?
now if cables are pulled (jump pair)
and car 1 dies, then car 1 battery or alternator is dead.
we test the battery first, we charge it and load test it (2 tools)

IF FAILS this test the BATTERY IS USELESS.
OR GET the BATTERY CAR 1 TESTING IN CAR STORE FOR FREE.
OK BATTERY GOOD BUT ALTERNATOR BAD.
NEW BATTERY STARTS THE CAR, AND IF ALTERNATOR IS GOOD
THE VOLTAGE ON THE BATTERY IS 13 TO 15VDC, BeLOW THAT , THE ALTERNATOR IS BAD. OR ITS FUSES are BLOWN.
OR BELT TO ALT IS LOOSE OR FELL OFF.

best is own a battery charger.
and if battery reaches, 12..6vdc rested it may be a good battery.

drain dead battery cranking is 100% normal !!!!!
we use a charger to diagnose and test all engine or FAIL hard.
not told order here.
why was it towed?
what does car do now , battery charged or jump started.
lets assume battery is now charged ( it must be !!!!)
and all fuses check good, skip NONE!@
then it still cranks fast.
does not start now/ yes or no/??????
if yes battery voltage must be 13 to 15vdc with meter.
if below that the alternator is dead, or its 3 fuse blown
or worse if alternator is PCM controlled

charge the battery with the tool named the same charger.

Probably need an expert on wiring harness ..not a dealer.. just an old school independent shop. Car been sitting too long ..ign parts old n worn also. Buy a haynes manual at parts or library sec629 has chilton repair volumes.

there is a short in the system that is connected to that relay/fuse. Could also be melted wires if you tried to ever jump start it from a car, start position on a charger or jump start box. Jump starting a motorcycle should never be done. The gauge of wires on a motorcycle are much lighter than vehicles.
It is VERY rare but i have seen batteries that are reversed polarity. Check to make sure battery is 12v + when you test it. Not 12v -

Its possible the charger is telling you the battery is too dead for the charger to work. A safety feature to keep from burning up the charger.
I'm not aware of any fuses between the jumping post and the battery. You may have a short in the car that is draining power.

The motor home battery I couldn't teel you but if you're talking about the vattery for yhe charger, it's located in the Passenger side inside the trunk. There is a cover over it that has to be removed to get access to it. If jumping, there are posts next to the battery I believe designed just forr jumping. I would REALLY suggest just charging the motor home batteries or using a different vehicle to use. Have found on your kind of vehicle that sometimes when getting jumped or visa versa That it causes an electrical problem. there is a fuse link in the wiring directly (sort of) from the battery to the alternator. Have seen this fuse link blown a lot and MANY people change the alternator thinking the alt. is bad beause the battery goes dead not to mention the car letting you know thta there is a charging problem.Hope this helps.....

sounds like might have cooked the regulator and the c.d.i. and the stator unit will need cheeking to

Yes this will defiantly blow the main engine fuse. This fuse is located in the engine compartment and is usually bolted down with 10mm bolts.

not a fuse or relay problem but a flat/dead battery
have the battery load tested and have the charge circuit tested by an accredited auto electrician to ensure that it is charging the battery

Apart from the fuse box in the engine bay there is a fuse repository behind the coin alcove underneath the boot release. Fuse 3 for the lighter (I think) was blown. I replaced it and now the climate control console responds and the display lights up.
